Madge’s current obsession, Brazilian male model Jesus Luz, 21 – whom she met on the South American wing of her Sticky & Sweet tour – is putting all of his eggs into the Material Mom’s basket and using her name and the resulting publicity to demand huge prices and build his career.

Brazilian spies told Glamurama.com.br, “All the modeling agencies came after him, but he chose Ford Models because [photographer and Madonna pal] Steven Klein had a talk with Katie Ford and convinced her that Jesus is, in fact, holy material.”

Sergio Mattos, the owner of 40 Graus Models and Luz’s former agent, says that after meeting Madonna, Jesus simply disappeared: “He stopped answering his phone, his mother quit her job . . . But I wish him the best. And now I have a new Jesus,” Mattos, who just signed a contract with Spanish model Jesus Perez, told the Web site. “This is a much better Jesus, and he’s not a fan of Madonna’s.”

Luz might be overestimating the value of his association with Madonna. “He was asking for some $135,000 a show. He did the same job last year for a mere $225,” said a Brazilian source. “A lot of people are contacting him but because he keeps raising his rates, they are changing their minds.”

Luz was supposed to fly to London last week to meet with Madonna, but “he had problems with his passport,” the insider said. “He didn’t even have a passport until like a month ago.”

When told he wouldn’t be allowed on the flight. he “went to party with some friends at Bar Secreto in Sao Paolo instead. A lot of girls were trying to get his attention, but he ignored them and just drank the Veuve Clicquot the bar owner sent over for him.”

Luz is expected to get his passport issues solved by tomorrow when he’ll fly to meet Madonna in London for his 22nd birthday.
